Answer:
The answer is "check the worksheet is not read only"
Explanation:
The read only mode is used for read the file data, and it doesn't allows the user to update the file, and for updating the worksheet we should check iut does not open in the read-only mode.
If it is open, then we close it and for close we goto the office button and click on the tools option after that goto general setting, in this there is a check box for turn off the read-only mode.
The requirements are mainly written in a feature style notation, using some state charts,
context diagrams and other techniques to describe certain parts of the system. See, for
example, Software Requirements - Styles and Techniques [Lauesen00].
The functional requirements are divided into four sections. The three modules in figure 1
are developed by separate groups, each responsible for unit testing. All requirements for
the taxi, central and communication link component are written in a feature style notation.
In addition, a special part of the taxi component is the positioning system. This is dealt
with separately since there are special requirements present on this component.
The functional requirements consist of four sections: Taxi (3.1), Central (3.2), Communication
link (3.3) and Positioning system (3.4).
Answer: Stratified sample
Explanation:
For preparing samples of various data of companies and enterprises we need to apply probability distribution to different samples of data. Here in the question we are to apply a representative sample from a list of 200 customers who have complained about errors in their statement. So here we can apply stratified sampling where we can divide the 200 customers into separate groups. These sub groups of the customers are known as stratas. These stratas are selected based on certain characteristics which can be identified among the customers group. Here we can form subgroups based on the type of complain that has been lodged by the customer and selecting 5 customers from four zip codes. Then it would be easy to apply probability distribution to the sub groups to derive information from them.
This process would also enable a more easier and cheaper way of sampling the customer data.
